BRAZILIAN HERNIA AND ABDOMINAL WALL SOCIETY STATEMENT ON LARGE HIATAL HERNIAS MANAGEMENT.

Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index above 35, age over 70 years, and the presence of comorbidities. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, a case-by-case analysis of surgical risk factors such as age, obesity, and comorbidities should be taken into consideration. Attention should also be paid to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual labor, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of large hiatal hernias in high-volume centers, with experienced surgeons.

BRAZILIAN HERNIA AND ABDOMINAL WALL SOCIETY STATEMENT ON LARGE HIATAL HERNIAS MANAGEMENT / Posição da Sociedade Brasileira de Hérnia e Parede Abdominal sobre o tratamento de grandes hérnias de hiato

Large hiatal hernias (LHH) besides being more prevalent in the elderly, have different clinical presentation: fewer reflux, more mechanical symptoms and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease (GERD-related), sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index (BMI above 35), age over 70 years and presence of comorbidity. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, case-by-case analysis of surgical risk factors such as age, obesity and comorbidities, should be taken under consideration. One should also pay attention to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual workers, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of LHH in high-volume centers, with experienced surgeons.

As grandes hérnias de hiato (HHG), além de serem mais prevalentes em idosos, têm apresentação clínica diferente: menos refluxo, mais sintomas mecânicos e maior possibilidade de complicações agudas e potencialmente fatais, como vólvulo gástrico, isquemia e perfuração mediastinal visceral. Assim, as indicações cirúrgicas são distintas das hérnias de hiato por deslizamento, relacionadas à doença do refluxo gastroesofágico (DRGE). A azia tende a ser menos intensa, enquanto os sintomas de dor no peito, tosse, desconforto e cansaço são relatados com maior frequência. Queixas de vômitos e disfagia podem sugerir a presença de volvo gástrico associado. São encontrados sinais de deficiência de ferro e anemia. A indicação cirúrgica ainda é controversa e foi anteriormente baseada na alta mortalidade relatada em cirurgias de emergência para volvo gástrico. A mortalidade pós-operatória está especialmente relacionada a três fatores: índice de massa corporal (IMC acima de 35), idade superior a 70 anos e presença de comorbidades. A cirurgia eletiva minimamente invasiva deve ser oferecida a indivíduos sintomáticos, com desempenho bom ou razoável, independentemente da faixa etária. Em pacientes assintomáticos e oligossintomáticos, além de obviamente identificar o desejo do paciente, deve-se levar em consideração a análise caso a caso dos fatores de risco cirúrgico, como idade, obesidade e comorbidades. Deve-se atentar também para situações de maior dificuldade técnica e riscos de migração aguda por aumento da pressão abdominal (abdominoplastia, trabalhos manuais, doenças espásticas). Alternativas técnicas como fundoplicatura parcial e gastropexia anterior podem ser consideradas. Ressaltamos a importância da realização de procedimentos cirúrgicos nos casos de GHH em centros de grande volume, com cirurgiões experientes.

VITAMIN D DEFICIENCY AND PARATOHOMMONIUM INCREASE IN LATE POSTOPERATIVE GASTRIC BYPASS IN ROUX-EN-Y.

BACKGROUND: Roux-en-Y gastric bypass patients can experience changes in calcium metabolism and hyperparathyroidism secondary to vitamin D deficiency. AIM: To evaluate nutritional deficiencies related to the calcium metabolism of patients undergoing gastric bypass with a 10-year follow-up. METHOD: This is a longitudinal retrospective study of patients submitted to Roux-en-Y gastric bypass at a multidisciplinary clinic located in the Brazilian southeast region. The study investigated the results of the following biochemical tests: serum calcium, ionized calcium, vitamin D, and parathormone (PTH). The generalized estimating equations (GEE) determined the nutritional deficiencies using a significance level of 5%. RESULTS: Among the patients who finished the study (120 months), 82.86% (n=29) had vitamin D deficiency, and 41.94% (n=13) had high PTH. Postoperative time had a significant effect on PTH (p=0.0059). The percentages of patients with vitamin D, serum calcium, and ionized calcium deficiencies did not change significantly over time. CONCLUSION: One of the outcomes was vitamin D deficiency associated with secondary hyperparathyroidism. These findings reaffirm the importance of monitoring the bone metabolism of patients submitted to Roux-en-Y gastric bypass. HEADINGS: Calcium deficiency. Vitamin D deficiency. Secondary hyperparathyroidism.

Metabolic Changes Up to 10 years After Gastric Bypass.

OBJECTIVE: The aim of this study was to investigate the lipid and glycemic profiles of patients up to 10 years after Roux-en-Y gastric bypass. METHOD: A retrospective, longitudinal study was conducted at a multidisciplinary center for the treatment of obesity in the state of São Paulo, Brazil. The study included 150 patients submitted to unbanded laparoscopic Roux-en-Y gastric bypass. The metabolic profile included total cholesterol and fractions, triglycerides, and fasting glucose. The patients were examined before and 3, 6, 12, 24, 48, 72, 96, and 120 months after surgery. Statistical analyses included the generalized estimating equations (GEE) and the Wilcoxon test at a significance level of 5%. RESULTS: All postoperative fasting glucose, total cholesterol, and triglyceride (p < 0.0001) test results were significantly lower than the preoperative test results. Low-density lipoprotein cholesterol (LDL-c) differed significantly in all but the 120-month follow-up (p = 0.0129). High-density lipoprotein cholesterol (HDL-c) was significantly higher 12, 24, 48, and 72 months after surgery (p < 0.001) and also 120 months after surgery (p = 0.0002). CONCLUSION: Gastric bypass promoted the control of metabolic diseases inherent to obesity as long as 10 years after surgery.

Resumo Racional: Pacientes submetidos ao bypass gástrico em Y-de-Roux, podem apresentar alterações do metabolismo do cálcio e hiperparatireoidismo secundário à deficiência de vitamina D. Objetivo: Avaliar as deficiências nutricionais relacionadas ao metabolismo do cálcio de pacientes submetidos à bypass gástrico em Y-de-Roux, com seguimento de 10 anos. Método: Um estudo retrospectivo longitudinal foi conduzido com pacientes submetidos à bypass gástrico em Y-de-Roux, em uma Clínica Multidisciplinar no Sudeste do Brasil. Investigou-se a frequência do acompanhamento médico e nutricional e os exames bioquímicos de cálcio sérico, cálcio iônico, vitamina D e paratormônio (PTH). Para a análise das deficiências nutricionais, foram utilizadas as Equações de Estimativas Generalizadas (EEG), com nível de significância de 5%. Resultados: Dos pacientes que permaneceram no estudo até o final (120 meses), 82,86% (29), apresentaram níveis de deficiência de vitamina D e 41,94% (13) apresentaram PTH elevado. O efeito do tempo foi significativo para o PTH (p=0,0059). Para a vitamina D, cálcio sérico e cálcio iônico, o percentual de deficiência manteve-se constante ao longo do tempo, sem diferença significativa entre os tempos. Conclusão: A deficiência de vitamina D, associada ao hiperparatireoidismo secundário, foi um desfecho encontrado. Tais achados reafirmam a importância do cuidado com o metabolismo ósseo, em pacientes submetidos à bypass gástrico em Y-de-Roux.

Tela de polipropileno no reparo laparoscópico de grandes hérnias hiatais: aspectos técnicos / The polypropylene mesh in the laparoscopic repair of large hiatal hernias: technical aspects

RACIONAL: A cirurgia minimamente invasiva ganhou rapidamente papel fundamental no tratamento da doença do refluxo gastroesofágico. Entretanto, o melhor método para as grandes hérnias paraesofágicas (tipos III e IV) ainda está em discussão. O uso de próteses para reforço da hiatoplastia tem sido proposto por diversos autores, no intuito de diminuir as altas taxas de recidivas encontradas nesses pacientes. Riscos de estenose e erosão da prótese são as complicações mais preocupantes quando se pensa em aplicar uma prótese no hiato esofágico. OBJETIVO: Demonstrar a técnica cirúrgica e resultados do uso de um modelo de tela idealizado no serviço dos autores para reforçar a hiatoplastia em grandes hérnias de hiato. MÉTODOS: Uma prótese de polipropileno foi aplicada para reforço da hiatoplastia em pacientes com grandes hérnias de hiato (Tipos II a IV de Hill). A prótese era cortada em forma de U, com sutura de cateter de silicone na borda côncava que ficaria em contato com o esôfago. Após sua fixação sobre a hiatoplastia, toda prótese era recoberta por gordura do omento maior, impedindo contato com o fundo gástrico ou fundoplicatura. RESULTADOS: De 1999 a 2012, esta técnica foi utilizada em 70 pacientes. Eram 52 do sexo feminino e 18 do sexo masculino, com idades variando de 32 a 83 anos (média de 63 anos). Em 48 (68,6%) pacientes, tratava-se de hérnias primárias e em 22 (31,4%) era recidivada após operação antirrefluxo. O único óbito ocorreu por sepse (1,4%) no 22o dia pós-operatório em caso com laceração da sutura da fundoplicatura causando fístula gastropleural. Não houve relação direta com o uso da prótese. Seguimento de seis meses ou mais foi obtido em 60 pacientes (85,7%), variando de seis a 146 meses (média de 49 meses). Todos os pacientes foram submetidos à entrevista clínica e pelo menos uma endoscopia e/ou radiografia contrastada no período de acompanhamento. Durante o seguimento, não foram observadas complicações (estenose ou erosão) relacionadas com a prótese. CONCLUSÃO: O uso do modelo de prótese de polipropileno descrito é seguro, desde que observados os aspectos técnicos de sua implantação.

BACKGROUND: The minimally invasive surgery has gained rapidly important role in the treatment of gastroesophageal reflux disease. However, the best method to treat large paraesophageal hernias (type III and IV) is still under discussion. The use of prosthetics for enhancing the crural repair has been proposed by several authors in order to reduce the high relapse rates found in these patients. AIM: To demonstrate the technique and surgical results in using an idealized polypropylene mesh for the strengthening of the cruroraphy in large hiatal hernias. METHODS: Was applied the polypropylene mesh to reinforce the hiatal closure in large hernias - types II to IV in Hill's classification - with a primary or recurrent hiatal defect greater than 5 cm, in a series of 70 patients. The prosthesis was done cutting a polypropylene mesh in a U-shape, adapted to the dimensions found in the intraoperative field and coating the inner edge (which will have direct contact with the esophagus) with a silicon catheter. This was achieved by removing a small longitudinal segment of the catheter and then inserting the edge of the cut mesh, fixing with running nylon 5-0 suture. RESULTS: From 1999 to 2012, this technique was used in 70 patients. There were 52 females and 18 males, aged 32-83 years (mean 63 years). In 48 (68.6%) patients, paraesophageal hernia was primary and in 22 (31.4%), it was relapse after antireflux surgery. The only case of death in this series (1.4%) occurred on 22nd postoperative day in one patient (74 y) that had a laceration of the sutures on the fundoplication, causing gastropleural fistula and death. There was no relationship with the use of the prosthesis. A follow-up of six months or more was achieved in 60 patients (85.7%), ranging from six to 146 months (mean 49 months). All patients have at least one follow-up endoscopy or esophageal contrast examination, and a clinical interview. In this follow-up period, no cases of complications related to the prosthesis (stenosis or erosion) were observed. CONCLUSION: The use of this model of polypropylene mesh is safe if the technical aspects of its placement are followed carefully.

Esofagogastrectomia vídeo-assistida para adenocarcinoma da transição esofagogástrica / Video-assisted esophagogastrectomy in esophagastric transition adenocarcinoma

RACIONAL: Nas últimas décadas observou-se expressivo aumento na incidência de adenocarcinoma da transição esofagogástrica. Concomitante a este aumento, houve progresso na cirurgia minimamente invasiva. OBJETIVO: Relatar a experiência com a técnica de esofagectomia vídeo-assistida, transhiatal para o tratamento de adenocarcinoma da transição esofagogástrica. MÉTODOS: Indicou-se a técnica em 30 pacientes, com predominância do sexo masculino (73%) e idade média de 55 anos. Após avaliação laparoscópica, 19 pacientes foram operados por técnica vídeo-assistida. RESULTADOS: O tempo cirúrgico variou de 4 a 5 horas. Houve necessidade de colocação de dreno torácico em 12 pacientes (63%). Dois (10,5%) apresentaram fístula na anastomose cervical. Houve um óbito devido à fistula intratorácica da linha de grampos. Excluindo este paciente, o estadio pós-operatóro mostrou três (16,7%) pacientes no estadio I, dois (11%) IIa, três (16,7%) IIb, seis (33,3%) III e quatro (22,2%) no estadio IV. A sobrevida global média foi de 25,5 meses (3 a 105 meses), e quando separada em estádios, foi 53,3 meses até estádio IIa e 15,8 meses em estado IIb ou superior. CONCLUSÃO: A cirurgia minimamente invasiva pode ser alternativa no tratamento do adenocarcinoma da transição esofagogástrica.

BACKGROUND: In the last decades an overwhelming increase in the incidence of esophagogastric transition adenocarcinomas has been observed. Jointly to this increase, there has also been progress in minimal invasive surgery. AIM: To relate the experience with video-assisted esophagectomy, transhiatal for the treatment of esophagogastric transition adenocarcinoma. METHODS: The technique was indicated to 30 patients, predominantly male (73%) with an average age of 55 years. After laparoscopic evaluation, 19 patients were operated on using the video-assisted technique. RESULTS: Surgical time varied between 4 and 5 hours. Toracic drains had to be applied in 12 patients (63%). Two (10,5%) had cervical anastomosis fistulas. One death occurred due to intratoracic fistula in the clamp line. Excluding this patient, post-operative state demonstrated three (16,7%) patients in stage I, two (11%) in stage IIa, three (16,7%) in IIb, six (33,3%) in III and four (22,2%) in stage IV. The overall life span was an average of 25,5 months (three to 105 months), and when categorized into stages, it reached 53,3 months up to stage IIa and 15,8 months in stage IIb or higher. CONCLUSION: Minimal invasive surgery can be an alternative in the treatment of esophagogastric transition adenocarcinoma.

Impacto da cirurgia bariátrica tipo capella modificado sobre a perda ponderal em pacientes com obesidade mórbida / Impact of bariatric surgery modified capella type on ponderal loss in patients with morbid obesity

Objetivo: Avaliar a perda ponderal no período pós-operatório de 12 meses, de pacientessubmetidos à gastroplastia redutora laparoscópica. Métodos: Foi realizado um estudo prospectivo com 90 pacientes portadores de obesidademórbida submetidos a gastroplastia redutora laparoscópica “tipo Capellamodificado”.

Para a comparação de medidas entre 2 grupos, foi utilizado oteste de Mann-Whitney e para explicar a variabilidade das medidas em funçãodos fatores tempo de seguimento, idade e sexo, foi utilizada a análise de variância.As correlações foram realizadas pelo coeficiente de Spearman, sendo adotadonível de significância de 5% (p<0,05)

Avaliação endoscópica das valvuloplastias anti-refluxo: uma proposta de classificação / Antireflux surgery: a proposed classification

A grande difusão da cirurgia por videolaposcopia no tratamento da doença do refluxo gastroesofágico trouxe consigo a necessidade de avaliar seus resultados. Uma das maneiras de fazê-lo é através da endoscopia, analisando morfologicamente as fundoplicaturas. No presente estudo, avalia-se o aspecto endoscópico de 169 válvulas, em diferentes períodos pós-operatórios, para propor uma classificação. Os autores dividem, morfologicamente, as fundoplicaturas em cinco grupos: válvula tipo I, com uma ou duas pregas gástricas envolvendo o endoscópio; tipo II, com três ou quatro pregas envolvendo o endoscópio; tipo III, com cinco ou mais pregas envolvendo o endoscópio; tipo IV, número qualquer de pregas, porém com abertura do anel hiatal; e tipo V, sendo a válvula desfeita, compregas irregulares, e com recidiva de esofagite. No estudo, foram encontradas cinco fundoplicaturas do tipo 1,81 do tipo II, 60 do tipo III, 16 do tipo IV e 7 do tipo V

Tumor fibroso solitário retrorretal: relato de caso / Retrorectal solitary fibrous tumor: report of a case

Tumor fibroso solitário (TFS) é um raro tumor de partes moles que foi descrito pela primeira vez em 1931 por Klemperer e Rabin, porém, mais recentemente tem sido descrito em outras localizaçöes (superfícies serosas ou näo serosas) extrapleurais. É uma neoplasia de fibroblastos, mais precisamente derivada de células mesenquimais, com diferenciaçäo multidirecional sendo por este motivo pouco diagnosticada e confundida com outras neoplasias. As células tumorais mostram reatividade imunohistoquímica para CD-34 e vimentina, e säo negativas para relato de TFS localizado no espaço pré-sacral e também discutimos as dificuldades diagnósticas, clínicas e histopatológicas, assim como o tratamento cirúrgico realizado

Paraganglioma gangliocítico do duodeno: relato de caso com hemorragia digestiva alta / Duodenal gangliocytic paraganglioma: case report with upper diggestive haemorrhage

Relata-se um caso raro de paraganglioma gangliocítico do duodeno com apresentaçao clínica inicial de hemorragia digestiva alta. O tumor estava localizado na transiçao entre a segunda e a terceira porçoes do duodeno. O diagnóstico histopatológico final, com áreas semelhantes a paraganglioma associadas com áreas de tumor carcinóide e ganglioneuroma, foi confirmado pelo estudo imunoistoquímico com positividade para NSE, cromatogranina e proteína S-100. A paciente é do sexo feminino, com 41 anos de idade e tem dez meses de seguimento clínico, sem qualquer evidência de recidiva da neoplasia.
